Please see the above given phone numbers. I need to replace all spaces, hyphen, period, brackets and leading 0 etc from these numbers. I need this format +447469186974

If number has leading plus sign then don't replace it otherwise I have to concatenate + sign with it.

E.G

+39 235 6595750 in this number I just need to remove spaces.

+44 (0)181 446 5697 in this i need to removes spaces and brackets and 0 in between brackets i.e (0)

07825 893217 in this I need to replace leading 0 with + sign and开发者_运维问答 remove spaces

(415) 706 2001 in this replace '(' with + sign and remove ')' and spaces.

'please reply by email' This is the entry in phone number field and I just need to ignore this.

+48.40.23755432 Remove period in phone number

(765) 959-1504 Remove brackets and spaces and hyphen and add + sign in front of number.

7798724250 just need to add + sign in front of number

00 44 (0) 20 7660-4650 Need to remove leading 0 I.E '00' remove spaces and brackets and 0 in between brackets and hyphen and add + sign in front of number

Only leading '0' will be replaced not anyother occourence of '0'

The desired result is +447769146971

Should I use nested REPLACE, CHARINDES, PATINDES for each char I want to replace?

Edit: I don't have to update these numbers in db. I just want to use these numbers in my query to match these numbers with numbers in call log db. In call log db format is always like this +447769146971

Thanks.

give this a try:

SET NOCOUNT ON
DECLARE @Phone table (PhoneNo varchar(50))
INSERT INTO @Phone VALUES ('+39 235 6595750')
INSERT INTO @Phone VALUES ('19874624611')

EDIT

based on OP's latest edit: I don't have to update these numbers in db. I just want to use these numbers in my query to match these numbers... why on earth would you want to format the number each time you run your query?? store the formatted numbers in the DB and then just join on them. Even if you just make a PERSISTED computed column or an view with an indexed on this formatted number, you'd have much better performance.

One solution would be to Create a function

 Create Function ExtractDigits( @inVal varChar(50), @EliminateLeadingZeroes TinyInt)
 Returns VarChar(50)
 As
 Begin
     Declare @outVal VarChar(50)
     Set @outVal = ''
     Declare @C Char(1)
     While Len(@Inval) > 0 Begin
         Set @C = Left(@InVal, 1)
         Set @InVal = SubString(@InVal, 2, Len(@InVal) -1)
         If @C Between '0' And '9'
             Set @outVal = @outVal + @C
     End
     If @EliminateLeadingZeroes = 1
        While Left(@outVal,1) = '0'
             Set @OutVal = Substring(@OutVal,2,Len(OitVal) -1)
     Return @OutVal
End

Then write Update Statement like this:

While Exists (Select * From table 
              Where Phone Not Like'+[0-9]%'
Update table Set 
    Phone = '+' + dbo.ExtractDigits(Phone, 1)
Where Phone Not Like'+[0-9]%'
